Odd, this bios version isn't listed on Lenovo's website. It is newer than the x230 bios version that I know to have the bug, so perhaps Lenovo fixed the problem. Care to attach your ACPI tables?

It's also possible that it works because you're using a different window manager, so you most likely wouldn't be using gnome-settings-daemon. You could check /sys/class/backlight/*/{brightness,actual_brightness} and see how the values are changing in response to the brightness keys.
